Recently discovered alongside its sister compounds KV_{3}Sb_{5} and RbV_{3}Sb_{5}, CsV_{3}Sb_{5} crystallizes with an ideal kagome network of vanadium and antimonene layers separated by alkali metal ions. This work presents the electronic properties of CsV_{3}Sb_{5}, demonstrating bulk superconductivity in single crystals with a T_{c}=2.5  K. The normal state electronic structure is studied via angle-resolved photoemission spectroscopy and density-functional theory, which categorize CsV_{3}Sb_…

TLDR
Here the spectroscopic results showed that the short bimolecular triplex Hn:Pn could be formed in acidic conditions and further extending to neutral pH as n = 4, and the data presented here may be useful in defining the experimental conditions necessary to stabilize triplex DNA.
